Abstract

Abstract

BaZr_0.9Y_0.1O₃ with perovskite structure was prepared by solid-phase reaction method and used as support to prepare Fe₂O₃ based catalysts. X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM) were used to observe the crystal phase structure and microscopic morphology of the prepared catalysts. The catalyst performance for the reverse water gas shift reaction was also investigated. The results showed that the supported catalyst has better catalytic activity when the BaZr_0.9Y_0.1O₃ powder was calcined at 1200℃ for 5 h. BaZr_0.9Y_0.1O₃ has an obvious catalytic effect on the reverse water gas reaction, and the Fe₂O₃-supported catalyst can significantly promote CO₂ reduction. Moreover, loading small amount of Fe₂O₃ has apparent effect on the reactivity of the catalyst. When the space velocity was 1.13 h^-1, the CO yield can reach 31% at 650℃. Carbon deposition on the catalyst during the CO₂ reduction process was taking place in a low rate, leading to a significant increase in the CO yield in the process of cooling-down experiment. In addition, the activity of the catalyst did not significantly decrease after a long period of reaction, which proved that the activity of the prepared catalyst was relatively stable.
